question 11 of 20
you drop a ball from a height of 10 meters. each time the ball bounces, it reaches a lower height. why does the ball lose height after each time it hits the ground?
a. some of its kinetic energy is transformed into potential energy each time bounces upward.
b. some of its kinetic energy is transformed into thermal energy because of friction between the floor and ball.
c. some of its potential energy is transformed into kinetic energy each time it falls.
d. some of its thermal energy is transformed into potential energy by the force of gravity each time it bounces.

Explanation:

When the ball hits the ground, there is friction between the ball and the floor. This friction causes some of the ball's kinetic energy (energy of motion) to be converted into thermal energy (heat), reducing the energy available for the ball to bounce back to its original height.

Answer:

B. Some of its kinetic energy is transformed into thermal energy because of friction between the floor and ball.
